@khof lets hope you wont need it. PMR can burn itself out. Mine was gone in 6 months. I know that is not the case with everyone. A WBC reaction to the biologics is not a side effect to some either. Kevzara is an immune blocker so the lowered WBC can be troublesome. You should be able to stop taking the Kevzara without the withdrawals so lets just hope the PMR does not return. Good luck.
